Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612766, here are decompositions:

7 + 31612759 = 31612766
13 + 31612753 = 31612766
19 + 31612747 = 31612766
37 + 31612729 = 31612766
103 + 31612663 = 31612766
139 + 31612627 = 31612766
193 + 31612573 = 31612766
313 + 31612453 = 31612766

Showing the first eight; more decompositions exist.
